Abstract: An image forming apparatus includes an image forming portion, an image reading portion, an analysis processing portion, a generation processing portion, and a printing processing portion. The image forming portion forms an image on a paper sheet. The image reading portion reads a first image from a printed side of a used paper sheet supplied from a sheet feed portion. The analysis processing portion analyzes content of the first image read by the image reading portion. The generation processing portion generates, based on the content of the first image analyzed by the analysis processing portion, a second image that degrades visibility of the first image when the second image is superimposed on the first image. The printing processing portion causes the image forming portion to execute a printing process such that the second image generated by the generation processing portion is superimposed on the first image on the printed side.

Abstract: A display input device includes a touch screen and a control unit. When the control unit determines that a scroll operation is performed, it controls the touch screen to start scroll processing to scroll display content on the screen. After the control unit controls the touch screen to start the scroll processing, when it determines that an adjust operation is performed on the touch screen in which a contact body is moved while keeping contact with the touch screen, it changes scroll speed of the scroll processing by the touch screen in accordance with a contact position of the contact body performing the adjust operation on the touch screen.

Abstract: A radio relay station provided with: a donor-side transceiver unit which transmits and receives a donor-side signal, at which a first frequency band is used, to and from a radio base station; a service-side transceiver unit which transmits and receives a service-side signal, at which a second frequency band adjacent to the first frequency band is used, to and from a radio terminal; and a control unit and a control unit which control the donor-side transceiver unit and service-side transceiver unit respectively. The donor-side transceiver unit, when the service-side signal has been received, measures the signal level of the service-side signal at the first frequency band. The control unit and the control unit adjust the shift amount for the second frequency band at the frequency shifter so as to lower the signal level.

Abstract: The radio communication system has a radio base station, a radio relay station connectable to the radio base station, and a radio terminal configured to connect to the radio base station. The radio base station notifies the radio terminal of identification information for a predetermined number of relay stations based on the number of radio relay stations that can be simultaneously connected to the radio base station. When the radio relay station is connected to the radio base station, identification information for any one of the relay stations is assigned to the radio relay station. The radio terminal performs a cell search based on the relay station identification information.

Abstract: A communication system of the invention includes a communication terminal correctable to first and second communication networks, and a controller for controlling service provision to the communication terminal according to which one of the first and second communication networks the communication terminal is connected to. The communication terminal includes: a reception determination unit for determining a reception condition of a control signal transmitted from the first communication network; and a notification transmitter for transmitting, to the controller, a notification indicating that the control signal can be received when the reception condition satisfies a certain requirement.
